Problem sorted with new upgrade to 6.9.5

Version 6.9.3

This problem causes a fatal error and the page will stop loading

Notice: Undefined variable: comment_Item in /home/calstock/public_html/inc/comments/model/_comment.class.php on line 2535
Fatal error: Call to a member function get_title() on a non-object in /home/calstock/public_html/inc/comments/model/_comment.class.php on line 2535

Wonder why the variable is undefined or moreso I suppose, where the variable should have been defined?>
